将 REST API 请求 json 值提取到"放心"中的变量

Question

我们必须使用响应值验证在 REST API 请求有效负载中发送的值，尝试了以下内容并能够打印 JSON 数组。如何获取请求 JSON 正文数组中的特定对象。

请求有效负载 ：

{
"Testinfo":{
"abc":2,
"xyz":"2020-01-01"
},
"Details":{
"eductation":{
"test1":9,
"test2":100,
"test3":50
},
"neweductiona":{
"test1":"value",
"test2":"Draws"
}
}
}

法典：

jsonObject = (JSONObject) JSONValue.parse(request);
JSONObject Testinfo =    (JSONObject) jsonObject.get("Testinfo");
JSONObject Details =     (JSONObject) jsonObject.get("Details");
System.err.println("Testinfo value in the request is: " + Testinfo);
System.err.println("Details value in the request is: " + Details);

输出：

{
"abc":2,
"xyz":"2020-01-01"

},
{
"eductation":{
"test1":9,
"test2":100,
"test3":50
},
"neweductiona":{
"test1":"value",
"test2":"Draws",
}

如何获取特定值，例如"详细信息.eductation.test3">

在下面尝试

JSONArray jsonArray = (JSONArray) JSONValue.parse(request)

但收到错误为：

java.lang.ClassCastException: net.minidev.json.JSONObject cannot be cast to net.minidev.json.JSONArray

请指导。

Answer 1

使用 JSONPath

String json = "{rn" + "   "Testinfo": {rn" + "        "abc": 2,rn"
+ "     "xyz": "2020-01-01"rn" + "rn" + "rn" + "  },rn" + "rn" + "    "Details": {rn"
+ "     "eductation": {rn" + "          "test1": 9,rn" + "          "test2": 100,rn"
+ "         "test3": 50rn" + "      },rn" + "     "neweductiona": {rn"
+ "         "test1": "value",rn" + "          "test2": "Draws",rn"
+ "         "test3": 50rn" + "rn" + "     }rn" + "  }rn" + "}";
JsonPath js = new JsonPath(json);
System.out.println("Value is : "+js.getString("Details.eductation.test3"));

输出：

值为 ： 50
